Summary

  • Add deviceInfo.platform (android | ios) to the mobile noise login ClientPayload, defaulting to Android for backward compatibility
  • Map iOS to UserAgent.Platform.IOS and default distributionChannel to APPSTORE (overridable)
  • Export WA_MOBILE_PLATFORMS / WaMobilePlatform and cover Android/iOS paths in unit tests

Test plan

  • node --import tsx --test src/transport/noise/__tests__/WaMobileClientPayload.test.ts
  • Confirm an existing Android mobile session still connects without setting platform
  • Confirm an iOS deviceInfo advertises UserAgent.Platform.IOS and App Store distribution in the login payload

Review in cubic

How do review limits work?

CodeRabbit enforces per-developer PR review limits within each organization.

For paid Pro and Pro+ reviews, CodeRabbit uses a developer's included PR review attempts over the past 7 days to set the current hourly allowance. At typical activity levels, the full plan allowance applies. Higher sustained activity can lower the allowance until earlier attempts leave the 7-day window.

📝 Walkthrough

Walkthrough

Mobile login payloads now support Android and iOS platform settings, platform validation, distribution defaults, and additional device metadata. The public transport and authentication exports expose the new platform type and constants.

Changes

Mobile platform payload

Layer / File(s) Summary
Platform contracts and exports
src/transport/noise/WaMobileClientPayload.ts, src/transport/index.ts, src/auth/types.ts
The mobile transport API exports platform constants and types. Device information accepts platform, device type, distribution channel, and experiment ID fields.
Platform resolution and payload encoding
src/transport/noise/WaMobileClientPayload.ts, src/transport/noise/__tests__/WaMobileClientPayload.test.ts
Payload construction defaults to Android, validates platforms, defaults iOS distribution to APPSTORE, preserves explicit overrides, and encodes device metadata. Tests cover these cases.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to a5775

The iOS login-payload test should verify that the App Store distribution field is actually encoded, not merely decoded to its zero value; the PR is otherwise mergeable with this bounded follow-up.

not add validation unless required elsewhere; correct the documented throw
contract while preserving existing parsing behavior.

Assert APPSTORE field presence.

APPSTORE is zero-valued. Line 252 also passes when the encoder omits distributionChannel and the decoder returns the scalar default. Assert own-property presence before comparing the enum value.

Proposed fix
     assert.equal(ua.deviceModelType, 'iPhone 16 Pro')
     assert.equal(ua.deviceType, proto.ClientPayload.UserAgent.DeviceType.PHONE)
+    assert.equal(Object.hasOwn(ua, 'distributionChannel'), true)
     assert.equal(ua.distributionChannel, proto.ClientPayload.UserAgent.DistributionChannel.APPSTORE)

The CI TypeScript lib is ES2020, so Object.hasOwn fails typecheck during npm ci build. Use hasOwnProperty.call instead.
